Long time lurker, first time poster (and thanks for all the help on previous puzzles!) –– this was the comment that confirmed I was on the right track after struggling for a while with the thematic phrase, so particular thanks to krauton today.
I have a question that I hope isn't too spoiler-y. I couldn't have cracked the numeric code without hints from this thread and having completed every other aspect of the endgame first... my question is: how did people approach decoding the string of digits into the five-word phrase? Am I missing some mathematical way of crunching it out, or was it simply a matter of staring at the string of numbers looking for something that resembled a thematic phrase that you'd already found? Or essentially reverse-engineering it at the end like I did? Thanks in advance.
